Controlled Bass Mayhem

Ugritone Bass Channel Strip — Help & User Guide

Welcome

Charlie Bauerfeind's bass chain in a box. Three and a half decades of low-end engineering for Helloween, Blind Guardian, Motörhead, Saxon, Van Canto and beyond — distilled into seven modules and one signal path designed to do one thing: turn a raw DI into a weapon.

Drop it on the DI track. Start turning knobs. Stop when the floor moves.

Quick Start

1. Insert Controlled Bass Mayhem on your bass DI track.
2. Set Gain Stage to match your DAW's reference level (most modern sessions = -18 dB).
3. Press Easy in the top right corner.
4. Browse the Presets — "Mega Sizzle" is a good starting point for aggressive metal, others are organised by style and bass type.
5. Adjust Input Gain until the input meter peaks around -6 dB.
6. Use Global Dry/Wet to taste — full wet is normal.

That's it.

Easy Mode vs. Full Mode

The Easy / Full toggle in the top right corner switches between two views:

• Easy Mode — Macro controls only. Load a preset, tweak input/output, get back to recording.
• Full Mode — Every module, every parameter, exposed. The view shown in the main screenshot.

Both modes use the same engine. Easy Mode just hides what you don't need to see right now.

Global Controls (Header Section)

These controls sit at the top of the plugin and act on the entire chain.

Setting Gain Stage Correctly

If your DAW is running at typical modern mixing levels (peaks around -6 to -3 dBFS, average around -18 dBFS), use -18 dB.

If you're working with mastering-style hot signals or hardware-modelled headroom workflows, use -24 dB.

0 dB is for legacy or unusual workflows where the DI hits the plugin at full DAW scale.

The Signal Chain

Controlled Bass Mayhem routes the top row through two frequency-separated paths. After the top row, the signals merge back into one for the final three modules.

                              ┌─── Bass Band ──────────────────────┐
                              │   Compressor → Preamp               │
Input → Frequency Split ────┤                                      ├─→ Equalizer → Harmonic Shaper → Multiband → Output
                              │                                      │
                              └─── Treble Band ────────────────────┘
                                  Compressor → Preamp → Brutalizer

The Frequency Split is the secret weapon. Sub-lows and string attack are two completely different beasts — splitting them lets you compress the low end for weight and the high end for grit, independently, with no compromise.

Reading the UI: In Full Mode, the top row shows both paths side by side. The leftmost Compressor and Preamp process the Bass Band (everything below the split frequency). The rightmost Compressor, Preamp and Brutalizer process the Treble Band (everything above the split frequency). The Frequency Split module sits between them as a visual marker of the split point.

Each module has a power button (top-left of its panel) to bypass it individually, and a Dry/Wet knob (top-right) for per-module parallel blending.

Module Reference

1. Frequency Split

The fork in the road. Splits the bass signal into two frequency bands.

2. Compressor (Bass Band & Treble Band)

There are two independent compressors — one per band. Each is a musical, dual-character compressor with two switchable tube models for harmonic colouration. The two compressors are identical in design but allow you to tune each band completely separately: weight on the low end, attack on the high end.

Charlie's approach:

• Bass Band compressor: Slower attack (let the transient pass), moderate ratio (3:1–4:1), more Tube A for warmth. This is where the bass gets its body and weight.
• Treble Band compressor: Faster attack (catch the pick attack), higher ratio (6:1 or more for aggression), more Tube B for harmonic excitement. This is where the bass gets its definition and bite.

3. Preamp (Bass Band & Treble Band)

Two independent transformer-based preamps. Each features dual switchable transformer models, a stepped low shelf, a sweepable mid peak, and a fixed high shelf — a classic console-style channel strip. One per band, each free to colour its own frequency range.

Charlie's approach:

• Bass Band preamp: Subtle Trafo A drive, low shelf at 60 or 110 Hz for chest, mid peak around 200–400 Hz to control or accentuate body.
• Treble Band preamp: Heavier transformer drive (especially Trafo B), mid peak in the growl region (700–1200 Hz), high shelf boost for air and presence.

4. Brutalizer (Treble Band only)

Multi-band saturation and clipping, applied only to the Treble Band. This is where the bass gets its bite, growl and pick-attack snarl — without smearing the low end, which is already on its own path.

Style Buttons

• Nice — Cleaner saturation curve. Subtler harmonic generation. Use on cleaner or finger-style bass tones.
• Push — Aggressive, gritty saturation. Strong odd-order harmonics. Cuts through dense mixes. Use on heavy or distorted bass tones.

5. Equalizer

Musical parametric EQ applied to the combined signal (post-merge). Four fully parametric bands plus dedicated high-pass and low-pass filters with selectable slopes.

Typical bass moves:

• HPF at 30–40 Hz / 24 dB/oct to remove sub-rumble — or leave off if your sub-bass is precious.
• Band 1: 250–350 Hz cut, narrow Q, to clear up boxiness.
• Band 2: 700–900 Hz boost, medium Q, for "growl" and finger definition.
• Band 3: 2–4 kHz boost, medium Q, for pick attack.
• Band 4: 8–10 kHz shelf boost for air and presence in the mix.

6. Harmonic Shaper

Multi-band harmonic saturator with per-band drive and gain compensation. Adds harmonic density to four targeted frequency regions, with resonant filters at the outer edges.

Global Controls

Outer Filters (HP and LP) — frame the processed range with resonant filters.

Four Saturation Bands: Bass / Presence A / Presence B / Treble

Each band drives its own saturation stage. Presence A and Presence B have sweepable centre frequencies; Bass and Treble are fixed-band shelves.

Charlie's approach: Most of the magic is in Presence A (typically dialled into the growl region) and Presence B (typically dialled into the pick-attack region). The Bass and Treble bands add warmth and air respectively. Keep Comp ON for tonal sculpting; turn it OFF when you specifically want a band to come forward in level as well as in colour.

7. Multiband

Four-band compressor followed by a global limiter. The final dynamic stage before output.

Crossover Frequencies (× markers between bands)

Per-Band Controls (4 bands: Low / Low-Mid / High-Mid / Hi)

Each band has its own compressor row with the following controls:

Charlie's approach: Use the Multiband sparingly — by the time the signal arrives here, most of the work is done. Set per-band thresholds so each band catches occasional peaks (a few dB of reduction maximum), not constant compression. The Low band benefits from slow attack to preserve fundamental punch; the Hi band benefits from fast attack to tame any residual string noise or fret buzz. The global limiter is your safety net — set it to Flat mode with a threshold that catches only the loudest peaks.

Presets

Presets cover the full chain including module on/off states, the per-band settings, and module order.

• Browsing: Click the Preset display, or use the arrow buttons to step.
• Saving: Click the disk icon to save your current state.
• Categories: Presets are organised by style (clean / driven / brutal / sub-heavy), by bass type (P-bass / J-bass / 5-string / drop-tuned), and by Charlie's signature session sounds. "Mega Sizzle" is one of the flagship presets — start there for aggressive metal.

When you start from a preset and turn a knob, the preset name will indicate the modified state. Save under a new name to keep your variation.

Charlie's Tips

• Set Gain Stage before anything else. Match it to your session's operating level. Every module in the chain is calibrated around it — get this wrong and you'll spend an hour wondering why the presets don't sound right.
• Solo each band while dialling. Bypass the other path's compressor and preamp temporarily — you'll understand the architecture in five minutes.
• The Frequency Split is not "set and forget". Move it. For drop-tuned material, push it lower (60–90 Hz). For finger-style fusion, push it higher (200–400 Hz). The whole chain reacts to where you put this.
• High ratios are where the aggression lives. Don't be afraid of 10:1 or higher on the Treble Band compressor with a fast attack.
• Comp ON for tone, OFF for level. In the Harmonic Shaper, leave Comp ON when you're sculpting character. Turn it OFF specifically when you want a band to push forward in volume as well as in harmonic content.
• The Brutalizer is only on the Treble Band. It cannot muddy the low end no matter how hard you push it. Push it hard.
• Don't compress in three places at once. Both band compressors plus the multiband plus the global limiter is four dynamic stages. If you're hitting more than 2–3 dB of reduction at each one, you're over-processing.
• DI in, weapon out. Controlled Bass Mayhem is designed for raw DIs. If you're feeding it an already-amped or pre-compressed signal, bypass the band compressors and preamps and let the chain start at the EQ or Harmonic Shaper.

Technical Specifications

Troubleshooting

The plugin doesn't load / shows an iLok error.
Make sure your iLok License Manager is up to date and your license is activated. The plugin requires iLok authorisation (USB key or iLok Cloud).

The presets sound off — too quiet, too loud, or too compressed.
Check Gain Stage. If your session is at modern peak levels and Gain Stage is set to 0 dB, every compressor and saturation stage will be working too hard. Set Gain Stage to -18 dB for typical mixing levels.

The bass disappears in the mix.
Bypass the Treble Band's compressor and preamp temporarily and check that the Frequency Split is where you actually want it. A too-high split point starves the Bass Band of fundamentals.

The bass is muddy in the low end.
Increase the Frequency Split, or reduce drive on the Bass Band preamp (lower Trafo A/B and Input). The Bass Band is conservative by design — if it's muddy, it's usually over-driven.

Latency is too high for tracking.
Reduce the Multiband Lookahead to 0 ms. Alternatively, bypass the Multiband entirely while tracking and re-enable it during mixing.

The EQ band doesn't seem to do anything.
Check the band's Type selector — if it's set to OFF, the band is fully bypassed (it doesn't matter what Frequency or Gain you've set).

I want to start over.
Load the preset "Init" (or the default preset) to reset every module to a neutral state.
